Valve cartridge for a sanitary fitting

Abstract

A valve cartridge for a sanitary fitting includes a cartridge housing with a disk control operated by a rotatable operating element. By turning the operating element, the disk control initially opens the water duct for cold water, starting from a closed position of the valve. When the operating element is turned further, the water passage for hot water is opened and, to the same extent the water duct for cold water is closed. In an end position, only the passage for hot water is open. A removable stop element can interact with a transverse bolt of the operating element to limit the adjustable range on one end so that the disk control cannot fully close, but can only be adjusted between the maximum opening position for cold water and the maximum opening position for hot water.

1 . A mixer cartridge for a sanitary fitting, including
 a cartridge housing,   a disk control arranged in the cartridge housing,   an inlet into the cartridge housing for hot water,   an inlet into the cartridge housing for cold water,   an outlet out of the cartridge housing for mixed water, as well as   an operating element,   controlling the disk control from a closed position through an opened position for cold water only, an opened position for cold and hot water to an opened position for hot water only, wherein   both end positions are determined each by a stop which is fixed to the housing, as well as having   an attachment facility for a removable stop element),   to limit the movement of the operating element on one side.   
     
     
         2 . A mixer cartridge according to  claim 1 , wherein the attachment facility is arranged in such a way that the removable stop element limits the movement of the operating element in a direction to the closed position or restricts said movement, if applicable. 
     
     
         3 . A mixer cartridge according to  claim 1 , wherein the attachment facility is embodied in such a way that the removable stop element limits the movement of the operating element in a direction to the opened position for hot water. 
     
     
         4 . A mixer cartridge according to  claim 1 , wherein the removable stop element can be attached in several angular positions. 
     
     
         5 . A mixer cartridge according to  claim 1 , wherein the removable stop element is pluggable, particularly in axial direction of the cartridge housing. 
     
     
         6 . A mixer cartridge according to  claim 1 , having a transverse bolt arranged on the operating element, designed as a movable element which may come into contact with the stop. 
     
     
         7 . A mixer cartridge according to  claim 6 , wherein at least one stop, particularly the removable stop element, is adapted to the cross-sectional shape of the transverse bolt. 
     
     
         8 . A mixer cartridge according to  claim 1 , wherein an only partially developed cover face of a housing upper part with approximately radially running end portions thereof establishes the stop which is fixed to the housing. 
     
     
         9 . A mixer cartridge according to  claim 1 , wherein the lateral surface area of the housing upper part features a toothing configured so as to fix the removable stop element.
